1. What are the 3 general zones of latitude? Map (shade) and label the zones.
2. Write a description of each zone’s climate.
3. What factors can affect a climate zone?
4. What zone is affected by seasons? How are they affected?
Use your textbook and Atlas to answer the
following questions.
Complete the written answers on the back
and map all components on the
front.
Climate Zones
The three major climate zones on the Earth are the polar, temperate, and tropical zones. Temperatures in these three climate zones are determined by angle of sun’s rays and are marked by latitudes into zones.
Climate ZonesTropic Zone
The tropical zones, which extend from 30 degrees north and south latitude to the equator (0 degrees) have high temperatures and high humidity. Precipitation in the tropical zones is usually very heavy during part of the year. Tropical zones are also known as low latitude climates.
Tropical climates have the warmest average yearly temperatures. There is no winter in tropical climates. In a tropical climate, the average temperature during the coldest month of the year does not fall below 18 degrees C.
In each hemisphere, the temperate zone is found between 60 and 30 degrees latitude. In the areas of the temperate zones farther from the equator, snow is common in the winter. In the areas of the temperate zones closer to the equator, rain normally falls all year round. But the average amount of precipitation is about the same throughout the temperate zones. Average temperatures in the temperate zones vary greatly. They range from about 5 C to more than 20 C. These temperatures fall between those of the polar and the tropical zones.
Climate ZonesTemperate Zones
Polar ZonesIn each hemisphere, the polar zone extends from the pole (90) to about 60 degrees latitude. Polar climates have the coldest average temperatures. Within the polar zones, the average yearly temperature remains below freezing (below O degrees C). Polar climates have no summer. Even during the warmest months of the year, the average temperature does not rise above 10 degrees C. There is little precipitation in the polar zones.

Climate Dolls
Identify the location for your doll. Where is she/he from?
Dress your doll appropriately for the climate zone and season.
Add an object to the hand that would represent the climate zone and region.
Attach an index card to the doll’s feet with the following information:
Location (Name & Coordinates)
Typical weather
Description of appropriate dress
Tools that may be utilized to adapt to weather conditions
Choose one of the following coordinate
locations and complete the tasks to create
your own paper doll.
60*N in January
10*N in February
35*N in July
40*S in August
Wrap-up QuestionExplain how the lines of latitude impact
the climate.
